Job 41:18

18. Translate: "his sneezing, causeth a light to shine." Amphibious animals, emerging after having long held their breath under water, respire by violently expelling the breath like one sneezing: in the effort the eyes which are usually directed towards the sun, seem to flash fire; or it is the expelled breath that, in the sun, seems to emit light. eyelids of morning--The Egyptian hieroglyphics paint the eyes of the crocodile as the symbol for morning, because the eyes appear the first thing, before the whole body emerges from the deep [Horæ Hierogliphicæ 1.65. Bochart].

Verse 18 By his neesings a light doth shine - It is very likely that this may be taken literally. When he spurts up the water out of his nostrils, the drops form a sort of iris or rainbow. We have seen this effect produced when, in certain situations and state of the atmosphere, water was thrown up forcibly, so as to be broken into small drops, which has occasioned an appearance like the rainbow. The eyelids of the morning - It is said that, under the water, the eyes of the crocodile are exceedingly dull; but when he lifts his head above water they sparkle with the greatest vivacity. Hence the Egyptians, in their hieroglyphics, made the eyes of the crocodile the emblem of the morning. Ανατολην λεγοντες δυο οφθαλμους κροκοδειλου ζωογραφουσι. - Horapp. Egypt. Ieroglyph., lib. i., c. 65. This is a most remarkable circumstance, casts light on ancient history, and shows the rigid correctness of the picture drawn above. The same figure is employed by the Greek poets. Χρυσεας ἡμερας βλεφαρον. "The eyelid of the golden day." Soph. Antig. ver. 103. Νυκτος αφεγγες βλεφαρον. "The darksome eyelid of the night." Eurip. Phaeniss. ver. 553.
